Smart Cuvettes

DUNEDIN, Fla., Oct. 3, 2007 -- SpectrEcology LLC said it has released the first "smart cuvettes" that measure pH and pO2. The pHuvette is an optical pH sensor embedded in the wall of a standard 1-cm cuvette. The sensor is a proprietary nanomaterial that traps bromcresol green pH indicator ions in a hydrophilic sol-gel cage.

The pHuvette can be used with any spectrophotometer to provide accurate stable measurements of the pH of the fluid contained in the cuvette.

pHoxyvette is a smart cuvette with an embedded oxygen sensor. Hydrophobic sol gel traps a ruthenium fluorescent compound. Oxygen is determined using phase fluorimetry to measure the fluorescence quenching. pHoxyvette has both pH and pO2 sensors.
